Category wrong assigned?

Dear all.
It seems that there is something i did wrong...
I have purchased for my client the Jsitemap Pro component which works very nice. And finally I have now my site map in spanish correct.
Please see: http://tantramassagehotel.net/es/contactar/mapa-del-sitio.html
But I see (When you click on "Nuestro blog) that the Category "Latest news" shows up here but this is ment only for the english part of the web and not for the spanish part.

And when you go to the english version http://tantramassagehotel.net/en/contact/site-map.html
you´ll see that the when you click on "our blog" there it shows "Ultimas Noticias". This should show up here.
This is quite strange as I tought that i had assigned correctly
- Ultimas Noticias (category) for the spanish part of the site
- Latest News (Category) is assigned for the english part of the site.

In the menu both for english as for spanish the correct category is selected.
Any idea as why there is this small mixup when showing this in the sitemap?

Hoping to hear from you again.
many thanks in advance...
Regards,
Paco
